Felfil EVO Extruder & Spooler Bundle

I bought this to reduce my overhead costs in my primary business of 3d printing, I've been looking for years for a workable solution to creating my own filament, and most ended up either way too expensive or complete failures. This is the best solution for those seeking something in the 1000$ range and is not afraid to get their hands a little dirty. The unity itself(The extruder) is solidly built, it is aluminum with a clear out shell, very sturdy and simple in its design. The components are I believe an Arduino that is well fanned and ventilated. Its function on the LCD is to the point and accurate, I've had no issues with it, unlike the spooler.

The spooler is that hot crazy girlfriend that you want to give up on but always seem to go back to even though you know it's going to piss you off. It's powered by a similar Arduino type machine, although there doesn't seem to be any fan on the casing itself because when it overheats from prolonged use, it does indeed freeze or severely delay the LCD screen and knobs settings. There are 4 settings on the spooler, Soft Medium, Hard, and Manual - thank god for manual. I had little to no luck with the preset setting of s,m,h but with manual, you can tweak all of the functions which allows for much easier operation and help a lot when you're using reground PLA. There is a filament measuring gauge on the spooler that I can verify is VERY accurate. It's a good machine for the price and worth experimenting with.
